I have tried everything with these sheets and i can't get anything to work!!!!!!!!!!!!!!!!!!! My death save, initiative, attack rolls, saving throws, skill checks, and spells don't work! I have custom macros for all of these things and it's not updating!

Custom macros do not update. You will need to recreate the macros yourself/manually unfortunately. The easiest way is to make the roll using the character sheet, push the up arrow in chat to get the last run command, and copy-paste the command into your macros.
